Billed as world's first race series exclusively for zero-emission electric cars, the EV Cup was originally scheduled to kick off its inaugural season in the U.K. at Silverstone on August 6, 2011. It has now been delayed and will start out in the U.S. with two race events in California at Laguna Seca in November and Auto Club Speedway in December, ahead of a full series launch in 2012. EV Cup organizers say they wanted to ensure that everything was ready before the series kicks off and cited safety requirements, car delivery schedules and the need for testing time as the reasons for the switch.
